horizontal lines - different heights on same page

[Anselm]

Hi there! I'm using short horizontal lines on my website. I've set the line height to 2px in the lay options menue. However, this does not seem to carry over consistently to all the lines I used/added since. So I've ended up with horizontal lines of different hights on one and the same page and I can't find a fix. Any ideas where I might have gone wrong? (It's the 2px one that I want, not the 1px one.) Best, Anselm

Dear @Anselm
for me the lines have the same thickness.
